Totally, I read this article by a physiotherapist who works with elite athletes, and she pointed out that the lockout rule is great for competition consistency but terrible for individual joint health. She mentioned that forcing full extension on every rep can aggravate hypermobile elbows or existing shoulder issues, which kinda proves your point about anatomy. It's ironic how powerlifting standards get treated like holy scripture when they're really just arbitrary lines drawn for judging convenience. Coaches probably parrot the cues because it's easier to teach one-size-fits-all rules than to assess each lifter's biomechanics. But that laziness ends up pushing people toward injuries instead of sustainable progress. I've seen folks in my gym grind for that lockout and wince every time, all because some YouTube guru said it's non-negotiable.
